This invention relates to improvements in pad making machines, and isparticularly adapted to be used in'connection with steel wool cuttingmachines, and machines used for assembling steel wool into ribbons.

It is particularly the object of this machine to receive ribbons ofsteel wool and to cut the ribbons into definite lengths, and after theribbons have been thus cut into lengths to first roll the sections ofribbon into bundles or rolls and thereafter lcompressing them into Hatpads.

It is particularly the object of this invention to provide in oneapparatus means for cutting ribbons of steel wool into definite lengthsand feeding'these sections of ribbon by means of a conveyor belt to aart of the device where these sectionsl are rst rolled and thereafter inthe same continuous action to flatten these rolls into flat pads.'

It is also an object of this invention to provide in connection with anapparatus of this kind means for feeding ribbons of steel Awool, ofdifferent thicknesses, and for that purpose the feeding apparatus isadapted t0 automatically adjust itself to the thicknesses of theribbons.

It is a further object of this invention to provide in connection withthe feeding, cutting, rolling, and flattening apparatus one means foroperating all of these parts at one time, and simultaneously with eachother so that as the Aribbons of steel wool are fed into one part of theapparatus the rolls will be fed out at another part.

It is also an object of this invention to provide an apparatus of thiskind that is automatic in all respects, easily operated and when startedneeds very little care or super- `vision during the running.

This apparatus is completely shown in side elevation in Fi re 1, vand isadapted to be used in connectlon with steel wool forming machines afterthe wool or strands of wool have been assembled into groups in the formof ribbons. The numeral 1 designates a platform supported by rollers 2.Upon the platform is a motor 3 used for power for operating all of themoving parts of the apparatus. This motor has the usual motor shaft,upon which, there is a pulley 4.

Extending transverse the platform, as'

a top plan view of the front 12 which is connected by a belt 13 to thepulley 12. This belt 13 travels over and around the pulleys 12 and 12 torotate shaft 10.

Extending from the platform 1 are uprights 14. In the drawings there areshown four of these uprights, constituting the rectangular frame, whichhas on the top thereof a rectangular frame 15. Extending from the frame15 are upright brackets 16, two in number, which support on the topthereof a shaft 17. Extending horizontally from the brackets 16 are arms20 which have in the outer ends thereof a shaft 21. On shaft 17 is agear 22 meshing with a gear 23 on shaft 21. On one end of the shaft. 21is a pulley 18 connected by a belt 19 with the pulley 9 on the shaft 5.

Supported in the brackets 16 between-the frame 15 and the shaft 17 is ashaft 24, which has adjacent one end thereofl a gear 25 in mesh withgear 22. On the front end of shaft 24, as shown in Figure 1, there is a1'0- tating feeder or notched roller 26. Extending from shaft 21 andpivotally supported thereby are links 27 which carry a shaft 28. Thisshaft 28 has a gear 29 meshing with ears 25 and 23, and also meshingwith each other. All of these gears are driven by the pulley 18 throughthe shaft 21 and rotate in unison.

On the front end of the shaft 28, as seen in Figure 1, is a feeder ornotched roller 30 which cooperates with the feeder or notched roller 26,for feeding ribbons of steel wool to the knives located beneath thenotched rollers so that definite lengths of the ribbon may be cut oftlas it passes through or between these rollers. It is obvious from an'examination of Figure 1 that these feeders or notched rollers may bespread apart, owing to the fact that the links 27 are pivoted at theirupper ends. To the lower ends of the links 27 there is attached one endof a spring 31, the other end ofwhich is attached to some part of thebrackets 16.

To one of the brackets 16 there are attached upright guides 32 flared attheir upper ends. To the lower parts of these upright guides is attacheda curved guide plate 33. The purpose of these guides is to receive 'andguide the ribbons of steel wool. The ribbon passes between the uprightguides 32 and over the curved guides 33, down between the feeders ornotched rollers 26 and 30, from which the ribbon is guided down betweentwo cutter blades,y hereinafter described.

In Figure 11 there is shown a steel wool machine from which strands ofsteel wool 32a are emerging and are collated or gathered together in aribbon by means of a hook 325. After the strands have been formed into aribbon, as shown in this figure. the ribbon is fed into the machine,where it is cut into proper lengths for being formed into pads.

On the outer end of shaft 10 is a pulley 34. Extending downward from theframe 15 are three brackets 35, which have sockets or holes therein inwhich a shaft 36 rotates. On the outer end of the shaft 36 is a pulley37 connected to pulley 34 by means of a belt 38. It is obvious that bythe rotation of the shaft 10 from the motor the shaft 36 is rotatedthrough belt 38.

Near the 'center of the shaft 36 is a beveled ear 39, while near the endthereof remote rom the pulley 37 is another beveled gear 40. kThe gear39 meshes with a beveled gear 41 upon a vertical shaft 42, rotating in ahousing 43. On the upper end of the shaft 42 is a beveled gear 44.Meshing with gear 40 is a gear 45 around a second vertical shaft 46,rotating in a housing 47. This shaft 46 has on its upper end a beveledgear 48.

Suitably supported upon the frame 15 are brackets 49, two in number, onesupporting for rotation a shaft 5() and the other a shaft 57. On one endof shaft 50 is a gear 51 meshing with the gear 44. On the other end ofthis shaft is a similar gear 51 which meshes with a gear 52 on avertical. shaft 53, rotatable and carried in a housing 54 suitablysupported by Athe frame 15. On the lower end of the shaft 53 is a cutterblade 55. Meshing with the gear 48 is a beveled gear 56 on thehorizontal shaft 57 in the other one of the two brackets 49. This shaftalso carries agear 58 which meshes with a gear'59 on a vertical shaft60, rotatably mounted in a housing 61 supported by the frame 15. On thelower end of the shaft 60 is a cutter blade 62 cooperating with a cutterblade 55 for cutting the steel wool ribbon into sections as it asses'down between the crimpers or notched rollers.

It is obvious from thepforegoing description that as the steel woolribbon is fed over the guide plate 33, down between the crimpers ornotched rollers it will be uided between the cutter blades and perioically be cut into short lengths, depending upon the speed of rotationof the shafts that carry the knives with relation to the shafts thatfeed the ribbon of steel wool.

Extending from the pulley 8 is a belt 63 which passes over a' pulley 64on a shaft 65. This shaft is located on the front or feeding end of therolling and pressing part of the apparatus. On the other end of theshaft 65 from the pulley 64 is a pulley 66. This shaft 65 is supportedin one end of the longr frame composed of two channel irons 67 held inspaced relation to each other,-as shown in Figure 2. Between thesechannel irons and upon shaft 65 is a pulley 68. The pulleys 64, 68 and66 are fastened upon the shaft 65 to rotate with it.

At the other end kof the frame and between the other ends of the channelirons is a pulley 69, near which there is an idler 70. Passwool ribbonas they drop from the cutting machine located immediately above thispart of the apparatus.

It is obvious from an examination of Flgure 1 that while the parts hereare shown in cooperation with each other and operated fromthe samesource of power, they may be separate and the cutting machine operatedindependent of the rolling and pressing part of the apparatus. Allthatis necessary to accomplish this is to remove the belt 63 from the pulley64, when the frame composed of the channel iron 67 may be removed fromthe other part of the apparatus.

While the upper part of the runway has slanting walls the lower part hasvertical walls, indicated by the numeral 73. Between these verticalwalls there is located a presser strip or board 74 attached adjustablythereto by means of brackets 75, having slots 7 5a to receive screws orbolts "7 5b located in the walls 73. Adjacent the lower end of thevertical walls 73 is a shaft 76: This shaft has on one end, outside ofthe vertical walls, a pulley 77 and between the Vertical walls a pulley78. Extending from the pulley 77 to pulley 66 is a belt 79 for thepurpose of causing the shaft 76 to rotate. On the extreme lower end ofthe vertical walls 73 is a shaft 80. O n this shaft is a pulley 81.Between theY pulley 81 and the pulley 78 is an idler 82. Around thepulleys 78 and 81 and around the idler 82 is a belt 83.

. It will be noted from an examination of' Figure 1 that the pulley 78is not in line with the pulley 81 and the idler 82 being somewhatelevated to provide a lar er entrance space between it andthe belt 1than between the other members and the belt 71.

For the purpose of supporting the channel .iron frame there is provideda truck `plat form 84 supported by rollers 85. Extending from theplatform is a frame 86 to which the channel 1rons are pivotally attachedat a point indicated by the numeral 87. On the ower -end of the channelirons adjacent-the pulleys 69 is a bracket 88, attached to the lower endof which are rollers 89. The purpose of the rollers 89 and 85 is topermit this part of the apparatus to be transported inde'- pendent ofthe parts supported by the rollers 2. As hereinbefore described, theseparts are separate one from-the otherfand may be operated independentlyone of the other and by means of these rollers they may be transportedfrom one place to another as separate and distinct units.

As the ribbons of steel wool are fed between the feeders or notchedrollers and cut' into short sections byI the knives, these sections fallupon the traveling belt and are fed down to the presser strip or board 74. When these 70 sections come in contact with the presser strip orboardthe frontend, on account o f the friction between the board and thesections of steel wool ribbons, the sections of ribbon begin to roll andare formed into round balls,

cylindrical in shape AThis is brought about from the fact that while theend of the ribbon is checked, on account of the fixed board, the ribbonis still traveling, due to the movement of the belt that supports it.

y As these round rolls 90 travel with the belt and roll under the stripor board they finally reach the lower end of the presser strip or boa-rdand come in contact with two traveling belts spaced one from the otherat the en-85 trance point, but as these belts travel they approach eachother and force what was at one' time round rolls of steel wool intoflat pads 91, rectangular in shape. After these pads have thus passedthrough the two rollers at the lower end ofthe frame they are ejected asa finished product. This last step of attening the 'rolls forms no partof this invention.
